very informative. thanks.

i think in cappuccino you do everything in the "backend". there's no need to write javascript/html/css ... which is good in a lot of ways (you can output source for different devices, and i'm even guessing you could generate different backends - php, .NET) - but i'm more interested in the js/AJAX everything model, lighter on the backend.

i've never worked in objectiveC/J but js seems nicer at first glance. but i may just be saying that so that i don't feel like i would miss something should we choose etxjs.

more feedback would be appreciated guys.

Actually it's the opposite, Cappuccino applications are mostly client-side, running on JavaScript. Objective-J is an extension to JavaScript, which gets compiled to JavaScript (either at runtime or ahead of time).

yes. but how is that generated js being served?

However you want. Nginx or Apache. It doesn't need a special server. Any interaction to the site/db/etc still goes through ruby or php or whatnot.

Any HTTP server. The runtime compilation takes place in the browser (the compiler is written in JavaScript). The pre-compilation uses a command line version of the compiler running in Rhino)

thanks. i think i'm sticking to js then.

ok. ok. i misunderstood. interesting. so why wouldn't i just write javascript? what is the value added? aside from the fact that i'm not coding in javascript (which i don't consider a negative)

JavaScript lacks several features useful in programming complex applications, namely classical inheritance, code importing, dynamic message dispatching. Objective-J adds these to JavaScript, but of course you still get all the features of JavaScript, since it's a superset of the language.

surely all these things and more can be accomplished with straight javascript. look at jquery! and extjs, prototype, ...

jquery has gone so far that it is starting to smell like a DSL. all in js.

thanks for the feedback.

yes. but how is that generated js being served?
